Double Fattiness

Double Fattiness Chinese is a 1988 Hong Kong comedy film directed by David Chiang and starring Bill Tung, Lydia Shum, Eric Tsang and Maggie Cheung.

Before Siufung died, she expressed a desire to ride a Chinese Wedding Sedan in the afterlife, which Chakshu and his son, Sonny, promises. When Siufung reaches the underworld, the wedding sedan arrived just in time to carry Siufung over the Neihe Bridge, where she will officially reach the underworld and be prepared for reincarnation. After proper registrations, Siufung who is grossly overweight attempted to cross the Neihe Bridge with the sedan, and the excessive weight caused the bridge to collapse. The sedan carriers, along with the sedan, fell to their death into the Neihe River, while Siufung was saved by the Spiritworld Keeper at the last moment.Since the Neihe Bridge was destroyed, Siufung cannot cross the bridge, thus creating an anomaly where Siufung is not officially dead, in spiritworld terms. The spiritworld keeper attempted to guide Siufung back to human life, where she can reenter her body, and be returned to life. However, Siufung was a little late, and her husband and son pressed a button to cremate Siufungs body. ........
